  • Drill bit
    Patent number: 10233696
    Abstract: A drag bit includes a blade extending from the bit body and supporting inner cutters proximate the longitudinal axis and outer cutters spaced from the longitudinal axis. The inner cutters are rotationally offset from the outer cutters. During operation the inner cutters deposit cut material in a channel that is contiguous with a channel that receives material cut by the outer cutters. The cutters and the contiguous channels flush agglomerating material from the slots.

  • UNIVERSAL JOINT
    Publication number: 20170002871
    Abstract: A universal joint assembled to a drill string transfers torque and axial force between two components where the shafts of the components are not completely aligned. The universal joint includes end members connected to opposite ends of a cable for connecting to components of the drill string. As the joint rotates the cable flexes to accommodate misalignment between the connected drill string components.
